yes -- naming conventions are fine but they cannot be used by automation
tools.
The YANG language says these strings have no meaning so tools cannot count
on them to have any meaning.

The issue here is whether there are standard extensions to tag YANG modules
or whether each tool vendor will have their own extensions instead.
It is not critical that the IETF provide these YANG extensions, but they
will get used one way or another.

CLRs always start out as clever little rules. They usually turn to
something else only
after some time.
